    So much for AC being a compatible with all other AC chipsets. Sounds like no matter what, youll only get rated speeds if you got every item in your system the same brand/series. Damned near impossible to do that.

    I'm not sure why you expected that a bunch of companies that all added proprietary extensions to their higher end G and N chips so they could slap bigger numbers on the front of the packages to sell to sheeple at your local boxmart wouldn't do the same with AC; but it was inevitable.

    Depends what you call "the rated speed".

    If you buy based on big numbers printed on the box, yes, you're probably going to be disappointed.

    If you buy based on the fact that a certain set of 802.11ac features are supported (and the common subset that all devices will support can easily be recognized by the WiFi alliance "802.11ac" logo) then that set will, indeed be supported. You're paying for a set of things like 3 channels, 80 channels wide, 256-QAM and HDPC, and everyone will support them.

    This has been the case since the dawn of time. Sensible people pay for the the SPEC features implemented well; idiots pay for NON-spec features.

    Was there any news about client chipsets? Would be nice to get MU-MIMO clients out earlier, so we can benefit from these improvements.

    "The PHY rates of the 2.4 GHz band along with the proprietary extensions (additional QAM-rates support for both bands that is outside the official specifications) take the peak WLAN PHY rates upwards of 9 Gbps."

    I think it is unfortunate that proprietary MSC modes (particularly in the established 11n domain) are been used to increase the aggregate maximum PHY data rate in order to reach 9 Gbps, which is then being aggressively marketed as "10G". Chipset suppliers should strive to maintain technical credibility in my view.

    You can hardly fault Quantenna for that! If I remember correctly, it was Broadcom that started with the proprietary QAM extensions for 802.11n (600 Mbps). Quantenna is a start-up and if I were them, I would try to play up the strengths as much as possible :) That said, I appreciate the fact that they were upfront about the proprietary extensions (unlike some other vendors I don't want to mention here - all the jargon in the PR, and when you dig deeper, much of it is proprietary).

    Awesome, I'm itching for proper reviews of Mu-mimo routers/ap which includes the prerequisites on how to make it work.
